 We report the results of a gamma-ray spectroscopic study of 211Po via the 208Pb(alpha,n) reaction at 24-MeV incident energy using a thick target. We observe 26 new gamma rays, allowing us to identify 18 states that were not observed in previous gamma-ray studies. In total, we observe 45 states below 2.0 MeV. A shell model calculation using the modified Kuo-Herling interaction developed by Warburton and Brown predicts 46 states below 2.0 MeV having spins of 21/2 and below, demonstrating the power of this calculation to provide detailed nuclear structure information on nuclei in the vicinity of 208Pb.
